I think one of the things people don't seem to realize on here is that Steem is mainly investor supported. Meaning the price depends on how much investors are willing to pay for it. It seems like a lot of people focus on metrics instead of the investors/buyers.
Facebook is mainly advertiser supported.
The advantage of being investor supported is there is less reliance on advertising dollars so there is less need to run ads and deliver metrics.
The downside to being investor supported is that you are reliant on investors to fund your operations and I think there could be a question of long-term viability if you rely solely on investors to fund your operations indefinitely. In addition if you use your blockchain holdings to fund your operations you could be on a path towards losing control of your blockchain.
You should be able to google some of the many perils of Facebook/"Fascistbook" if you don't already know them. lol

Apparently the marketing team reports to Elizabeth Powell the head of Head Of Communications & Advocacy link I'm not sure how many teams and employees Steemit has but I would guess at least a dozen if not 100 or perhaps even more.
It was "interesting" to see the alleged Steemit employee get fla**ed by a Steem witness on the post
